Determining
the source and the horizontal and vertical extent of contamination
in impacted media, whether resulting from historical industrial
activities, storage tanks, or past leakage and spillage, is essential
in determining risk liability. Contamination assessments range from
preliminary investigations as part of property transactions, for
example, to full scale risk assessments in accordance with the LDEQ
Risk Evaluation/Corrective Action Program (RECAP). The completion
of a proper assessment, taking into account the many parameters,
site specific information, and options necessary to conduct a risk
assessment of the facility, is vital for an accurate scientific
depiction of site conditions. Once a proper assessment is conducted,
evaluation of the site, with relation to the RECAP document, can
be made to determine the appropriate course of action. If necessary,
corrective or remedial actions must be initiated to control or halt
contaminant plume migration. Capturing and/or removing contamination
from the impacted media of concern are/is necessary to prevent further
company liability and protect the environment.

Hydro-Environmental Technology, Inc. professional staff has conducted
numerous contamination assessments at sites ranging from small
underground storage tank facilities to large scale industrial
facilities. In addition, HET has completed numerous risk assessments
in accordance with LDEQ's RECAP to evaluate the risk posed by
contaminants at various facilities and determination of the potential
for impacts to site usage. HET's experience offers the detail
of risk evaluation options tailored to site conditions to allow
for site management or the design and implementation of effective
and cost efficient remedial action systems.

Once the need to remediate or corrective actions are identified,
HET's design and knowledge of several remedial proven techniques
allow for a design that works best to limit impact liability,
allow for continued usage of the property, meet regulatory requirements,
and protect the environment. HET has designed remediation systems
for groundwater and soil treatment that range from monitored natural
attenuation to dual phase extraction and from activated carbon
and mini-defused air stripping canisters to soil vapor extraction
systems.
